COMPONENT AND FUCTION FINISH

13. VCO IC (Voltage Control Oscilator)
the function as frequency oscillator/generator that be sent to pass Tx(Tranceiver) and frequency that enter to pass part Rx (Receiver) so that being equal with radiated. beside that, this component also functioned as pulse voltage regulator from RF signal processor.

14. RX/TX 
as enter/out signal

15. LCD 
this component will functioned to display all activities from handphones, as media communication reads and write in handphone. 

16. KEYPAD 
this component functioneds as device input that give data command to cpu then processed and sent to other component related to handphone

17. INFRA RED 
infra red a tool that transfer data or program. But in general infra red used to send and receive data from computer to handphone or conversely. Infra red will work when facilities activate good in handphone and or in computer. But usually when computer that used kind laptop or notebox so this facilities detect of system operation at installation. Actually function infra red this is same as does data cable, only data cable direct linked will into handphone while infra red is not such. this apparatus work by using light infra red distance between handphone one with other may not far apart, must face to face, and doesn't shut a certain. 

18. BLUETOOTH 
this tool is used to transfer data or functioned as mediator between a equipment with other equipment. Facilities bluetooth exist in handphone usually used to send or get data from computer, handphone other, or conversely has also and use this facilities. The bluetooth function in handphone in principle same like infra red. simply procedure from bluetooth use frequency stripe or radiowave, for delivery distance or data acceptance doesn't like infrared, bluetooth has overplus can be used to send and get data concurrently at the time of same. beside that bluetooth has also surplus can be used without having to close to one another between sender equipment with receivers equipment, in general distance can achieve hundreds meter.

19. BATTERY 
the function as electricity current source to give electricity current in mobile phone. battery for handphone there what kind, that is: Nickel-Metal Hydrate (nimh), Lithium-Ion(Lion), and Lithium-Poly-Mer (Lipoly).

Component And Function Part 2

6. MCU (Master Control Unit) 

MCU is program or datas exist in handphone bound in audio IC, this data has permanent or from factory, like: handphone program version, IMEI, year maker, and phone code. In nokia generation dct-3, we can take this data from other handphone in good condition then can save it in computer as data reference (extention *. fls). One file *. fls extention keep two datas that is MCU and PPM if we use program flasher dct-3. But if use program griffin, ufs-3, prodigy, jaf, or program flasher newest another so the program permanent divided will be two, that is mcu and ppm, only to discern that MCU file usually ended with number 0 while PPM it is end with font/alphabet. But not all handphone kinds be taken the data, like handphone that belong to dct-4 or another new handphone because there aredata that provided by programmer. Usually extention from datas like mcu it’s permanent and number 0, then ppm also extention with font/alphabet, except for handphone nokia 3650,7650 and 6600, or new handphone extention cx or c1 to mcu.

 7. PPM 
This data is much the same with MCU, but only specialize in language, ringtone/polyphonic, and standard program from handphone. This data is is not has permanent or canbe chage and add new programs. 

8. IC RAM 
this component is basically is also data storage, but in character only temporary, because component in the work manner depend on electricity current that flow in series. if handphone deadens so directly data will lost by itself. This component is very related tight with activity CPU. ever greater Capacity from RAM so CPU in good performance, but if RAM damage so CPU can not work. 
 
9. Charging IC
this component works automatically moment charging battery, functioned to charge and regulate voltage charging battery that controlled by CPU by controlling IC. 

10. UI IC
functioned as that data controlling by CPU IC in vibrator, buzzer, led and has as automatic electric switch in handphone.
11. ic pa 
he function as amplify end signal that be radiated throught component antenna switch found on handphone. 
 
12. IC RF 

Functioned as signal controlling rx (receiver) and tx (tranceiver), so that every part can work well. This component consists of some part that is: If, Mixer, Oscilator, Detektor, Enkoder, Dekoder, Afc, Tone Frequency And Squelch.

several important components found on handphone alongs with the function

1. Power IC (CCONT) 
To distributed current and voltage 
 
2. Audio IC (COBBA) 
this IC has function as voice signal processor that enter from RF IC, then at strengthen and sustained to speaker, amplify that in advance by mic be electricity oscillation then sustained to RF IC, run command from CPU. in Audio IC also found PCM (Pulse Code Module) and EEPROM that functioned to read signal code receive from operator to suited with handphone imei. beside that also functioned to keep data’s has permanent like imei, phone code, etc. 
 
3. CPU IC
CPU is electronics component integration and will be functioned as according to the task each. this component has task very significant, because this component is brain from a handphone. Equally cpu centre from handphone system work. 
 
4. IC FLASH 
functioned as handphone data storage not permanent equally can be changed or add with datas in computer. this tool is same the function with hard disk in computer. 
 
5. EEPROM (Electrically Erase Programable Read Only Memory) 

this component functioned as data repository in handphone that designed doesn't irrespective electricity current existence from handphone, because there are special battery or have electricity current, usually this component keeps factory data likes imei1, imei 2, security code, program version and maker date. but for brand handphone nokia data newest product found on this component is irreversible.

Component in Mobile Phone

Fundamental component in cellular telephone set is grouped to be some part : 
1. Power 
    Power part is component that give voltage in every related component and work on command CPU
2. Signal (rx and tx) 
    Signal part component that regulate signal (in and out) and will send the data to cpu to be       cultivated or processed 
3. Data (operating system) 
     This data part functioneds as operating system that cultivate data and give command to      entire parts found on cellular telephone set 
4. Audio part 
   This part component that cultivates or work for voice vibration process that enter or secretory voice vibration 

Power part 
this power part is divided from several that components in cellular telephone set, that component is among others: 
1. Batteray 
2. Ic power supply 
3. Switch on/ off 
4. CPU 

When handphone in a state off, batteray give current/voltage to handphone, that is to ic PA, ic regulator, ic charging, ic interfaces 

Ic power have function to process and divide current / voltage from batteray then take outside stanby voltage to cpu 

When handphone on, CPU get negative voltage (-) from switch on/off, then cpu command to IC power supply for supplying current/voltage to every part in handphone 

In Charging process, current/voltage from charger enter to R fuse that functioned as fuse/safeguard in the event of overload current into charging IC. 

Current/ Voltage that enter to charging ic will be processed and be taked as output and must as same with batteray voltage. 

In charging ic found charging sense as data formed controlling that ic power supply, the function in the event of not appropriate with performance charging ic, so power ic will decide charging and will send data to CPU IC that charging is fail or not charging. 

Power supply will take output voltage after handphone in on state, except vbb voltage that functioned as stanby voltage.

If damage in power supply IC happen, there will be no stanby voltage / vbb from power supply.
